Collisions of microdrops of water

AbstractIn this paper, collisions of microdrops of water were studied. Experimental studies of microdrops become very difficult as the drop dimensions become extremely small, particularly when the drops are so small that they contain only a few thousand molecules. To overcome these physical limitations, we produced a model for the H2O molecule using molecular and atomic interaction forces. We then placed these molecules together to produce drops. Hence, using this new technique, we could study drops with no lower size limitations.To study the motions of these drops, large systems of second order nonlinear ordinary differential equations had to be solved numerically. The system of equations were solved using a CRAY Y-MP8/864 computer. To observe the motion of the drops, output data was transferred to a SGI IRIS 4D-70/GT graphics computer which drew three-dimensional pictures of the data
